Difference Between DX12 vs Vulkan

Compare DX12 vs Vulkan in performance, platform support, development complexity, and features. See which graphics API outdoes the other on Windows, Linux, Xbox, and for cross-platform development.

In today’s graphics development, we see a great discussion between DX12 vs Vulkan. Both APIs are in place to provide low-level access to GPU hardware, thereby reducing CPU overhead and maximizing performance. But when we look at DX12 vs Vulkan, we see that issues of platform support, development complexity, performance, and ecosystem play large roles.

Overview of DX12 vs Vulkan

To understand DX12 vs Vulkan, look at their origins.

DirectX 12 (DX12) is from Microsoft and is, for the most part, used in Windows PCs and Xbox consoles. It is very much a part of the Windows ecosystem.
Vulkan is a product of the Khronos Group. Also, it is a cross-platform API that supports Windows, Linux, and Android.

DX12 is targeted at Windows-centric platforms, while Vulkan is not tied to any platform.

Performance Comparison: DX12 vs Vulkan

When it comes to the performance of DX12 vs Vulkan, both APIs present similar features. They are low-level APIs that:

Reduce driver overhead
Allow multi-threaded command buffer creation
Provide explicit memory management
Offer better CPU utilization

In the field of real-world testing, what is seen is that for the most part, performance differences between DX12 and Vulkan are a result of driver optimization and developer implementation rather than the API on which they are based.

On Windows: we see that DX12 does a little better in terms of optimization because of Microsoft’s large role in the OS.
On Linux: we see that Vulkan tends to perform better as it is natively supported.

In most cases performance of DX12 and Vulkan is equal when both are properly optimized.

Platform Support: DX12 vs Vulkan

Platform support is a major issue in the dx12 vs vulkan decision.

DX12: For Windows and Xbox only.
Vulkan: Windows, Linux, Android.

In a project that is exclusive to Windows, DX12 is the go-to. But for cross-platform projects, Vulkan comes out on top in the DX12 vs Vulkan debate. For developers who go after PC, console, and mobile markets, Vulkan has it all.

Ease of Development: DX 12 vs Vulkan

Another major issue between DX12 and Vulkan is development complexity.

DX12 benefits from very tight integration with Windows tools, like Visual Studio. Also, the debugging and profiling tools are very well developed and user-friendly. In the Microsoft ecosystem, we see that DX12 is a more manageable solution.

Vulkan is also known for its verbose and explicit nature. It has in depth set up which is done out in the open. This does give the developer more control, but at the same time also increases the learning curve.

DX12 does, in many ways, outperform Vulkan in the DX12 vs Vulkan comparison, in particular for those that are already in the Windows development space.

Hardware and Driver Support: DX12 vs Vulkan

Both in DX12 and Vulkan, we see support for the latest GPUs from NVIDIA, AMD, and Intel. In the debate between DX12 and vulkan hardware compatibility is a tie. However, that is that DX12 updates, which tie to the Windows updates, but Vulkan, which has support in the GPU vendors and the Khronos ecosystem, for drivers that, at times, may affect performance and consistency.

In most cases, we see that between DX12 and vulkan hardware support is even across major GPU manufacturers.

Advanced Features: DX12 vs Vulkan

In the comparison of DX12 vs vulkan we see which features such as:

Ray tracing
Multi-threaded rendering
Explicit resource control
Advanced shader models

are available in both environments.

DX12 includes support for ray tracing in the form of DXR (DirectX Raytracing), and at the same time, Vulkan has its own set of ray tracing extensions. In terms of features, which is a point of comparison between the two, DX12 and Vulkan are very much at the same level.

Which Is Better: DX12 vs Vulkan?

The choice between DX12 vs Vulkan depends on your project.

Choose DX12 if:

You target Windows and Xbox only.
You prefer Microsoft’s development tools
You want tight OS integration

Choose Vulkan if:

You need cross-platform compatibility
You target Linux or Android
You want broader ecosystem flexibility

In DX12 and Vulkan, there isn’t a typical winner. Both are great at delivering high-performance graphics.

Conclusion

In terms of performance and efficiency, the DX12 and Vulkan comparison puts forth two very current graphics APIs. While DX12 does well with its integration into Windows and the Xbox, Vulkan does better in terms of wide-scale platform support and flexibility. In the end, which you choose between DX12 and Vulkan is based on your development goals, target platforms, and team expertise.
